TELEMATIC RED TIDES CONFERENCES WILL BE OFFERED BY IFOP
May 29th, 2021
As part of Fisheries Development Institute (IFOP) Harmful Algae Research Center (CREAN) regular work, within ASIPA program framework; Comprehensive Advice on Fishing and Aquaculture. During Monday, May 31rst, morning a closure workshop seminar will be held on “Management and monitoring of harmful algal blooms and marine toxins in the Pacific Ocean of south central Chile (36 ° – 44 ° s) , stage III, 2020 – 2021 Program “ and “management and monitoring of red tides in the Chilean fjord and channel system (stage XIV) 2020-2021 Program “, which between them cover up a very wide extension of the country’s coastline, covering from the extreme north of the Biobío region to the extreme south (Islotes Mariotti), in the Beagle Channel sector, the Magallanes region and Chilean Antarctica.
Both studies are aimed at providing reliable and timely information regarding harmful microalgae distribution and abundance, linked to what people call red tides, in addition to collecting oceanographic and meteorological information, also including data dissemination and distribution obtained through different platforms and social networks, both for the authority and for general public.
The seminar considers a total of 7 presentations that address various topics on different types of harmful microalgae, both on the coast exposed to the Pacific Ocean, and in the fjord and canal system in the south of the country.
After welcome greetings by the organizers and Fisheries and Aquaculture Undersecretariat, the seminar will begin with a presentation offered by Dr. Oscar Espinoza-González on “ Pacific Ocean of Central-South Chile Harmful Marine Algal Blooms and Toxins Progress and Challenges”Then Dr. Gonzalo Fuenzalida Del Río will refer to the use of molecular biology for these microalgae research through the conference called ” Phytoplankton monitoring through molecular methodologies implementation”; The third presentation will refer to a status that some microalgae present in their life cycle, known as cysts, which are deposited on the seabed and an important participation in the blooms, this will be in charge of Dr. Pablo Salgado Garrido and carries by title “Registry of dinoflagellate resistance cysts between the Biobío and Magallanes regions: Distribution, diversity and abundance”; To finalize the first conference block, the strategies that have been developed to distribute results and knowledge about these events to different segments of the community about red tides will be shown, a conference that will be given by Pamela Carbonell Arias, entitled “Dissemination Strategies linked to Harmful Algal Blooms and their effects ”.
After a brief interruption, the second block will begin with three lectures, referring to various harmful microalgae and the effect of environmental variables on their distribution and abundance, which is in charge of Dr. Javier Paredes-Mella. ” Salinity’s role , temperature and climatic patterns in FAN species of the genera Alexandrium, Protoceratium and Dinophysis dynamics “; Then, two blooms that have affected the extreme north of the fjords in the Los Lagos region will be presented separately in recent months, one referring to microalgae that produce toxins that affect people’s health, which will be in charge of Dr. Oscar Espinoza-González. “Flowering of Pseudo-nitzschia and domoic acid in the inland sea of Chiloé during the spring-summer 2020-2021” and finally the last presentation, referring to a recent flowering in the Comau fjord, which produced a significant mortality of fattening salmonids, which will be in charge of Dr. Jorge Mardones Sánchez. “Heterosigma akashiwo flowering in the Comau fjord in 2021: In situ and laboratory observations”.
The opportunity will be conducive to an exchange of opinions and discussion about these events, which in recent years have caused significant impacts on the social and economic environment.
